Experts said they are contributing to rising appearance anxiety among teens and want the internet giants to do more to limit harmful content.

One in four Brit youngsters is now more worried about how they look than their physical health. And calls by girls to Childline about body image fears went up 17 per cent in a year.

Katharine Wright, the Nuffield Council’s assistant director, said: “These things should not be available online.”

The report also called for a ban on offering cosmetic procedures to under-18s.

A Government spokesman said: “We live in a world where young people are under immense pressure on a daily basis about how they should look – it is ethically wrong for companies to exploit this and offer unnecessary cosmetic procedures to under-18s.
